ORTE_FILEM \- Open RTE MCA File Management (FileM) Framework: Overview of Open RTE's
FileM framework, and selected modules.  Open MPI 4.0.4
.
.\" **************************
.\"    Description Section
.\" **************************
.SH DESCRIPTION
.
.PP
FileM is a utility framework used by OpenRTE for a variety of purposes, including
the transport of checkpoint files, preloading user binaries, and preloading of user files.
.
.\" **********************************
.\"    Available Components Section
.\" **********************************
.SH AVAILABLE COMPONENTS
.PP
Open RTE currently ships with one FileM component: \fIrsh\fR.
.
.PP
The following MCA parameters apply to all components:
.
.TP 4
filem_base_verbose
Set the verbosity level for all components. Default is 0, or silent except on
error.
.
.
.\"   rsh Component
.\" ******************
.SS rsh FileM Component
.PP
The \fIrsh\fR component uses \fIrcp\fP or \fIscp\fP to do its file transfers. This component
requires the use of passwordless \fIrsh\fP or \fIssh\fP between all nodes.
.
.PP
The \fIrsh\fR component has the following MCA parameters:
.
.TP 4
filem_rsh_priority
The component's priority to use when selecting the most appropriate component
for a run.
.
.TP 4
filem_rsh_verbose
Set the verbosity level for this component. Default is 0, or silent except on
error.
.
.TP 4
filem_rsh_rcp
The program to use to copy files. Generally will be rcp or scp.
.
.TP 4
filem_rsh_rsh
The program used to remotely log into a given machine and remove files.
Generally will be rsh or ssh.
.
.\"   Special 'none' option
.\" ************************
.SS none FileM Component
.PP
The \fInone\fP component simply selects no FileM component. All of the FileM
function calls return immediately with ORTE_SUCCESS.
.
.PP
This component is the last component to be selected by default. This means that if
another component is available, and the \fInone\fP component was not explicity
requested then ORTE will attempt to activate all of the available components
before falling back to this component.
